Journal ArticleDOI
Effect of bunk management on feeding behavior, ruminal acidosis and performance of feedlot cattle: A review
Karen S Schwartzkopf-Genswein,Karen A. Beauchemin,D. J. Gibb,D. H. Crews,D. D. Hickman,M. Streeter,Tim A. McAllister +6 more
Journal ArticleDOI
Review: The use of direct fed microbials to mitigate pathogens and enhance production in cattle
TL;DR: This review focuses on the development of DFM that exhibit activity in cattle against potentially zoonotic pathogens such as Escherichia coli O157:H7, Sa...
Journal ArticleDOI
Effects of barley grain processing on the site and extent of digestion of beef feedlot finishing diets.
TL;DR: Results indicate that optimal degree of rolling for barley fed to feedlot cattle corresponded to a PI of 75% or lower, and coarsely rolled barley is not recommended because it resulted in the lowest digestibility and lowest microbial protein synthesis.
Journal ArticleDOI
Methane abatement strategies for cattle: Lipid supplementation of diets
TL;DR: In this paper, a study was conducted to investigate the impact of several lipid sources that supplied mainly long-chain fatty acids (FA) for their potential to reduce methane emissions from growing cattle.
Journal ArticleDOI

Renee M. Petri,T. Schwaiger,T. Schwaiger,Gregory B Penner,Karen A. Beauchemin,Robert J. Forster,John J McKinnon,Tim A. McAllister +7 more
TL;DR: Determining the metabolic roles of these key genera in the rumens of cattle fed high-grain diets could define a clinical microbial profile associated with ruminal acidosis.
